| Abstract: | The lowering of mining dilution ratio and loss ratio is one of major difficulties in front of mining researchers.In order to lower mining dilution ratio and loss ratio to an ideal level, some mesurements should be taken ,such as using a strict and rationable mining sequence,impoving the quality of mining design ,and enhancing construction management. |
